Abstract

This publication aims to describe the design, implementation, and verification of a fiber-optic wrist sensor based on the Bragg grating (FBG) for monitoring the heart rate (HR) of the human body. One of our primary goals was also to create a sensor suitable for measurements in harsh environments such as magnetic resonance imaging (MRI). For this reason, we used polylactic acid (PLA) material for the encapsulation of Bragg grating itself. This combination results in a sensor solution that is resistant to electromagnetic interference (EMI). Based on their previous agreement, the sensor has been properly and systematically tested based on a group of six volunteers of one sex. The acquired data were then processed and evaluated, using the absolute error (AE), relative error (RE), and its mean. The outcome of this study indicated an RE of 9.07 %, implying promising results and the first step of this study.
